HOW DOES A TANKLESS WATER HEATER WORK IN THE PHOENIX AREA
Tankless water heaters deliver an endless flow of hot water, If you’ve ever tried to fill a large bathtub and run out of hot water, it’s because your existing tank water heater isn’t designed to keep up with that kind of demand.
On the other hand, a single tankless water heater can deliver as much as 12.0 gallons of hot water per minute, non-stop, you'll never run out of hot water.
There are models that will make as little as 4.0 GPM, and many models in between. That’s the first advantage a tankless has over a tank water heater.
The best way I like to explain how a tankless work is to go back in time to 1897, see the first modern water heater was actually a tankless water heater... yes the old potbelly stove that was used to warm up the home and cook the family's dinner had an exhaust vent going through the roof, this pipe was very hot and at the time was called a "standpipe" a copper coil pipe was wrapped around this stand-pipe which transferred the heat to the copper coil, cool well water ran through this copper coil and as the water ran around and around inside the coiled pipe it became very hot and supplied the need for hot water, thus a tankless water heater was invented.
The same concept still takes place today in a modern tankless water heater, a copper coil pipe is in a copper box called a heat exchanger, and beneath this heat exchanger is a powerful flame that's called a burner, as demand for hot water, (someone opens a faucet) the tankless senses this flow and in a split second fire the burner, as the water travels around and around inside the coil pipe inside the heat exchanger it becomes very hot and then enters your homes hot water piping system and right to the faucet you have open and hot water is supplied, unlimited hot water until you close the faucet, then gas will shut off and no more hot water until the faucet or shower is turned on again.
Tankless water heaters only operate when demand for hot water is given (when a faucet is opened) if no hot was used for a week, the tankless never turns on, this saves you energy and that saves you money. A traditional 50-gallon tank water heater maintains a constant temperature of 125˚ - 130˚ degrees 24 hours a day, 365 days a year wasting energy when you don't need hot water.
